Ninja Warrior is back. After being conquered last year, Mount Midoriyama is angry. A tougher course with new obstacles will challenge the Ninjas like never before.

The second Heat sees the rise of a new breed of Ninja and the return of some of our greatest and most loved Ninjas as they battle it out on the toughest course we've ever seen.

It's Heat 3 and tonight sees the return of Ninja favourites as well as brand new Ninjas set to give the old guard a run for their money.

It's the final Heat for Season 5 of Australian Ninja Warrior's and the last chance for the Ninjas to secure a place in the Semi Finals. Will the furious Mt Midoriyama destroy their dreams and their chance of winning $200,000?

It's the first of the Semi Finals. With awe-inspiring obstacles, fan favourites and newbie Ninjas battle it out to make the Grand Finals with the Top 2 going head-to-head on the Semi Finals Power Tower.
